As some species of Fountaingrass will not survive cold winters, check which species you have, and if necessary grow it in a container that can be kept indoors during winter.

Many Pennisetum occur in the natural habitats of the Sulcata and Leopard tortoises and all are considered safe to feed, but they do have a reputation for accumulating oxalates and soaking up nitrates from the soil, so try to grow on a low-nitrogen compost.

Do not confuse with Miscanthus, which is also called Elephant Grass but is a different plant, or with other types of Millet, which belong to the same family but a different genus.
